Can you explain how to calculate mean median and mode?


assistant
Mean: The mean is determined by taking the sum of all values and dividing by the number of values. 

Median: The median is the middle value when the values are placed in order of size. If the number of values is odd, the median is the middle value; and if the number of values is even, the median is the average of the middle two values. 

Mode: The mode is the most commonly occurring value in a data set. If no values repeat, there is no mode.
